Academics

A 15.0 kg komatik sled is attached by a light cord to another 10.0 kg komatik sled. These tandem sleds are accelerated North by a dog team that apply a 175 N force to the lighter sled. The lighter sled is on ice so it has essentially no friction but the heavier sled is on rough snow (µ = 0.170) so it has some friction.

Find: a) the friction on the heavy sled. b) the acceleration of the system (both sleds are moving forward together). c) the magnitude of the tension in the cord connecting the two sleds.
